I personally don't do this anymore. But have in the past without issue.

When I used to cut them down and crimp a new end on, I did it for neatness. I'd crimp those aftermarket connectors. No solder. Never had a failure.

I stopped doing it because once cut, I always felt like I'd "devirginized" a servo. While I had faith in my home made connection, it annoyed me that somewhere in my mind I knew it wasn't factory quality. I also hated knowing it was permanently changed and couldn't really be swapped to a new application/model with ease.

Nothing was functionally wrong. It just gave me neurosis.

So I stopped defiling the nubile servos.

I found that folding the wire over itself and inserting it into a weave sleeve looked just as neat. And I no longer modified my servo allowing use in other applications.

My experience and 2c. Your servos. Your choice!

Did you have to seek help for your "post traumatic servo disorder"?

You felt better knowing that some little Chinese kid in a sweat shop did the crimping for you?

Probably done by machine. Welcome to the future. No need for employees anymore "some machine is doing that for you." Zager and Evans, "In The Year 2525 (Exordium et Terminus)", 1969

Watch at YouTube

Anyway, I agree with Aaron29. I feel like I've taken value away from a servo if the lead is shortened. For extensions in planks cutting the wires down to the minimum length is fine. No need to have excess wire flapping around in the fuselage or wing.

LOL. Now that you put it THAT way!

Still, the nubile servo is defiled!

BTW if you cut and crimp and then change your mind, you can send it in to Hobby Services or the like and get a new wire. I do that yearly to keep the wires from stiffening. They also get new gears and potentiometers on the visit to the servo shop. I fly a LOT and still my servos are so far out of warranty but going strong.

Really the DO or DO NOT of this whole thing is more psychological than anything. The heli will fly regardless of wire length. If you prefer, cut away. You can always get a new wire serviced before selling it.

Curious as to how come it has been said that solder would do more harm than good on a solid crimp connection? Maybe a bad solder job, but just a touch of solder would only seem to add to the strength of the bond. I can say a bad solder job that would not add to a crimp connection is where the solder is layed on so heavily it wicks up the wire and makes it rigid and or melting the rubber wire cover.

Solder tends to creep up the wire a bit and make it prone to crack/split upstream the connector.

Factory crimps don't have solder.

Correct! As solder gets wicked up the wire, that part gets stiff. Now the wire starts to flex at the point where the solder ends and the strain relief is not there. So potentially the failure will be right at that spot.

If you crimp, you don't have that weak point and the connector usually gives you some strain relief for the wire.

A good pair of crimpers is $400. A $40 dollar crimper gives you a $40 crimp. I won't fly with $40 crimps or aftermarket extensions made in someone's sweatshop with $40 crimpers.
Bullcrap. Do you honestly think they use top dollar tools to make your stuff in the Chinese factories, i.e. SWEATSHOPS? Do you honestly think those kids/slaves care more about their work then you would doing it yourself?

I have the $40 crimper from Hansen and it's a damned fine tool. Easy to use, too.

I haven't done either, but I have bought some used birds that have the wires looking real neat in weave sleeves with what appears to be a bit of heat shrink on the ends. If I can find a good source of weave sleeves I have an old 450 3d I'd like to practice on.

They're called wire braids and there are many different colors to choose from. I used then on both my birds. Ebay is a good start.

I found that Paracord is much much easier to work with than the mesh. It also comes in just about every color known to man. Lots of suppliers on the Internet. Just Google paracord.

I put all my wiring in braided loom and hated it.
Made everything too big and bulky.

Let me tell you this...getting the leads OUT of the loom is way harder than getting it in.lol...

I just went back to my old tried and true curly wires.
Just wrap them tight around a small allen wrench and they hold the shape.
I even wrap my two ailerons together and run the elevator through them as if the actual leads are the loom.

Curling them shortens them by about 60% and they'll still stretch to any length up to their full length.

I literally never use the word literally right.

Servo City sells a nice one for cheap. Don't remember the brand.
